Single Stage Centrifugal Compressor Development Kevin Finney Ray Zhou Xiaoyi Li Krishna Murty Jinying Zhu Brian Gulliver Dipjyoti Acharya July 23, 2003 Compressor MotorCoupler

Curved Blade Impellers –Balancing completed and parts returned Extra Motor and Controller Ordered –Should arrive September 5 th –Extra controller in rotation Straight Blade Impeller –Being sent to American Hoffman for balancing Inlet Guide Vane –Received from 3-Dimensional Engineering Status of Compressor Parts

Collector –Manufactured and assembled with pipe flanges –Ready for attachment to mass flow meter

Compressor Testing Motor Characterization –Free Spin Power Test

Compressor Testing Issues Controller Problem –Occurred after free spin test –Received new controller from Koford –Ran motor since and new controller works

Compressor Testing Blank Shaft Testing –Bearing and coupler losses –Shaft Alignment

Compressor Assembly Animation

Future of Compressor Development Run coupler and bearing test Attach pressure and temperature transducers Run compressor with curved and straight blade impellers Compare results of both impellers
